We received a message from a customer that the version 0.1 API will stop working as of Dec 6. Is this true? We developed a free WordPress plugin that has 8000+ active installs, based on the verion 0.1 API:
Moving to the new API is not viable as we do not want to pay for API calls for a plugin that is entirely free without ads. If the API will stop working we will need to delist the plugin asap.
That information is correct. Our v0.1 API will be retired as of Dec 6, 2016. Using our v2 API does not have a fee with it however. Unless Wordpress would have a fee on their side for updating the plugin, I do not know where the fee would come from.
I looked at the posts on the support forums for your plugin and see where you mention delisting your plugin.
If you are worried about how many calls you need to make on a daily basis then you can send an email to firstname.lastname@example.org with your current information such as API key and we can look over the details and see what options are available to you. Using our standard v2 API has a base amount of 10k calls per day with our normal API key and again that has no fee with it. Going beyond that is generally restricted to our partners and that is something we can look in to for you specifically once you email us.
The v2 API requires a Mashery account which is only free if below 4 calls/second and 10,000 calls/day. With 8000+ active installs (ie. 8000+ websites using this widget), this plugin is most likely going to exceed that limit.
We do our own admin of the Mashery accounts when they are used for Constant Contact. So we can decide what the limit is for each individual account. We can, if deemed appropriate, increase your limit above 10k calls per day. As I mentioned previously this is normally something we restrict to our partners; however there are exceptions. If you would like us to review your usage and look in to options for you please email us as email@example.com.
We had sent an email to webservices but was not offered any option to raise the API limit. So even if we are willing to rewrite the plugin to use the v2 API it may not work properly.
There is no way for us to contact the site owners using this plugin to notify them to stop using the widget. Has Constant Contact notified all customers who used the v0.1 API recently that it would stop working?
We did send a notification to all customers who used the v0.1 API within the past 6 months.
If you have any other questions, please let me know!

That's a great question. Yes, we are only discontinuing support of the v0.1 API. Anything that is currently using the v1.0 API will continue to work past December 6th 2016.
